A Crunch
A Crunch is when you do sit-ups, but you’re too lazy to actually do them right. You just bounce up and down like a sad, tired potato.
"I did a Crunch today. It took me 20 minutes to do 3 sit-ups."
My Crunch was so bad, my mom asked if I was in a trance.
I did a Crunch for 3 hours and still didn’t feel it.
